02_springboot部署-jar和-war的方式

一、部署jar包

1.在项目目录下，输入mvn install

2.输入以下命令运行

java -jar target/demo_zhang-0.0.1-SNAPSHOT.jar

3.http://127.0.0.1:8080/hello

二、部署war包

1.application新加@ServletComponentScan注解,且继承SpringBootServletInitializer

package com.example.demo_zhang;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
@ServletComponentScan
public class DemoZhangApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(DemoZhangApplication.class, args);
    }

}

2.pom.xml修改

在下添加

<packaging>war</packaging>

在<dependencies>中填入

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

3.在项目目录下，输入如下命令

mvn clean package

4.在项目目录的target中，找到demo_zhang-0.0.1-SNAPSHOT.war,修改名称为ROOT.war，然后移到Tomcat的webapps目录下。

5.运行Tomcat，并访问http://127.0.0.1:8080/hello
